[whitesox99]

Hi,

I am new to JSF and need some help can some one please tell me how to create a dynamic datatable with sorting functionality. I am reading data data from a database table and wants to build the datatable dynamically based on the columns returned. I know how to created a datatble with a fixed number of columns but can't figure out how to create a datatable dynamically with sort functionality. Any small example will help.

Thanks
